Baked zucchini, tomato and mozzarella casserole FAQ:

What size baking dish is recommended for this casserole?

A 9x13-inch baking dish is recommended for this recipe, as it allows enough space for layering the zucchini, tomatoes, and mozzarella evenly.

How do I know when the casserole is done baking?

The casserole is done baking when the cheese on top is golden brown and bubbly, typically achieved after about 40-45 minutes total baking time: 25 minutes covered with foil and an additional 15-20 minutes uncovered.

Can I use different types of cheese instead of mozzarella?

Yes, you can substitute mozzarella with cheeses like provolone, gouda, or a blend of Italian cheeses for different flavors while maintaining a similar melting quality.

How should I store leftover casserole?

Store leftover casserole in an airtight container in the refrigerator for up to 3-4 days. Reheat in the oven or microwave before serving.

Can I use frozen zucchini or tomatoes for this recipe?

While fresh vegetables are preferred for optimal texture and flavor, you can use frozen zucchini and tomatoes if thawed and drained, but note this may change the casserole's final texture.

Tips:

- Tip 1: Use a mandoline slicer to get evenly thin slices of zucchini and tomatoes, which ensures uniform cooking and a professional look.

- Tip 2: To avoid excess moisture in your casserole, lightly salt the zucchini slices and let them sit for 15 minutes before patting them dry. This helps remove some of the water content.

- Tip 3: Experiment with additional herbs and spices, such as basil, oregano, or thyme, to enhance the flavor profile of your casserole.

- Tip 4: For added richness, you can layer in some Parmesan cheese along with the mozzarella.

- Tip 5: If you prefer a crispy top layer, broil the casserole for the last 2-3 minutes of baking time.
